Several teams added important pieces at Thursday's trade deadline to bolster their roster. However, the Milwaukee Brewers were one of the least active teams in the market.Former Atlanta Braves pitcher and first-ballot Hall of Famer John Smoltz discussed the "biggest losers from the trade deadline" in Saturday's episode of "Flippin' Bats with Ben Verlander" podcast.When Verlander asked Smoltz about the biggest losers from the deadline, the legendary pitcher named the Milwaukee Brewers as the team that let him down the most because of their lack of activity. "The Milwaukee Brewers are having a fantastic year, and if I'm their fan base, I'm getting air coming out of the tire, I'm deflated," Smoltz said (7:00 onwards). "That doesn't mean they can't go on and go to the postseason."But if you're a fan of the Brewers, you're like, 'Please, we are having a monster year, if we add this or that and not just one player, a catcher.' I wouldn't call them the biggest losers. I would just call them a letdown.The Brewers have surprised many this season and are the best team in baseball with a 67-44 record. They occupy the top spot in the National League Central, holding a 2.0 lead over the Chicago Cubs. Smoltz feels their strong run could have made them a contender if they strengthened at the trade deadline."How many times can you do this? How many opportunities do you think you're gonna have? They're having an unbelievable year; there's nothing to take away from the Milwaukee Brewers and what they've put forth this year. But as the trade came and went, you can make an argument that they were one of the teams that barely did anything to increase their chances of a really good year."Brewers thrash Washington Nationals for historic sweepThe Brewers might not have added any major pieces to the roster at the deadline but the NL Central team are not showing any signs of slowing and Milwaukee blew away the Washington Nationals on Sunday.Milwaukee thrashed the Nationals 14-3 on Sunday to complete a three-game sweep. During the series, the Brewers had 56 hits, tying their franchise record for most hits in a three-game stretch, driving in 38 runs.The blistering start to August comes on the back of a 17-7 record in July, which included an 11-game winning streak.
